First of all, for best results and to avoid supports you need to print the file twice and glue the two together. This is my third try at this Batarang, and I am very happy with the result. It was all done personally, took about four hours to make, and was well worth it because it may be the most accurate design to this incredibly underrated Batarang design you can find for free. My first try is still on my profile, but this one is much better.
